Abstract

The taxonomic composition and quantitative characteristics of zooplankton and zoobenthos of several water bodies of natural origin have been studied in the Norilsk industrial region and adjacent territories a year after a technogenic accident. All age groups of most invertebrate species have been recorded at most sampling sites. Slightly disturbed watercourses are registered in the source of the Pyasina River and in the Daldykan River, located upstream the confluence of the Bezymyanny stream. These water bodies may serve as the background reservoirs for organizing restoration activities accompanied by an assessment of the ecological well-being of planktonic and bottom fauna of freshwater ecosystems.

技术事故后皮亚西诺湖流域水体中浮游动物和底栖动物的状况

摘要

技术事故发生一年后，在诺里尔斯克工业区和邻近地区对几个天然水体的浮游动物和底栖动物的分类组成和数量特征进行了研究。大多数无脊椎动物物种的所有年龄组都已在大多数采样点进行了记录。皮亚西纳河 (Pyasina River) 的源头和位于别济米亚尼 (Bezymyanny) 河交汇处上游的达尔迪坎河 (Daldykan River) 的水道受到轻微干扰。这些水体可以作为组织恢复活动的背景水库，同时评估淡水生态系统的浮游和底层动物群的生态福祉。
